One of the first questions customers ask us is how much acoustic underlay costs. In our experience, buyers are often surprised by the range — from budget options under £5/m² to premium systems over £30/m². Here is the honest breakdown.

Price Ranges by Product Type

Product Approx. Cost Per m² Performance
3mm rubber (54dB) Budget tier 54dB ΔLw
6mm rubber (74dB) Mid-range 74dB ΔLw
Cork-rubber composite Mid-range Good acoustic + thermal
SilentMat 15mm Premium Heavy use applications
12mm acoustic system Premium 30dB + 58dB full system

Is Cheap Acoustic Underlay Worth It?

In our experience, very cheap acoustic underlays (under £3/m²) typically have minimal real acoustic performance. The cheapest genuine acoustic product in our range is our 3mm rubber — it delivers real, measured 54dB improvement. Spending slightly more gets you significantly better results.

Total Project Cost

For a typical 20m² bedroom: 3mm rubber = very affordable. 6mm rubber = modest investment. The improvement in quality of life is disproportionate to the cost.
